PropertyFileSnitch

Determines the location of nodes by rack and data center.

This snitch uses a user-defined description of the network details located in the
cassandra-topology.properties file. Use this snitch when
your node IPs are not uniform or if you have complex replication grouping
requirements. When using this snitch, you can define your data center names to be
whatever you want. Make sure that the data center names you define correlate to the
name of your data centers in your keyspace options. Every node in the
cluster should be described in the
cassandra-topology.properties file, and this file should be
exactly the same on every node in the cluster.

Procedure

If you had non-uniform IPs and two physical data centers with two racks in
each, and a third logical data center for replicating analytics data, the
cassandra-topology.properties file might look like
this:
